To (diie/10m [it may concern:

.l Be 4itlknown that we. CHARLES L. BUCK- 'SjGHABrQ of the city, county,y and -State of .\e\\` York. andy limi. GERMAN); of Brooklyn, Kings-county. and State of )few York, citizens of the .nited States of America, have made a new-and usefuly improvement in apparatus,forperforating,fillets of paper for the automatic transmission of messages or for such other purposes as perforated tape of ,t his general character may be applicable.

VThe present invention is an improvement upon `that class oli-,perforating `machines shown in `lfnited States Letters Patent of Buckingham and Germann, No. 659,433, October 9, 1900., in whicvh is a punch head through which passes a fillet or band of paper, the latter being first prepared with a central row of perforations, wherein aper tures on each side of said central row are next perforated. ln this machine is also employed a feed wheel having )eripheral Apins which mesh with the centra holes of the tape both as it approaches the punch' head and emerges therefrom. By this means, the tape is held under tension on either side of the punch head, and thus it is that the outer holes may be punched in exact cross-alinement with those ofthe centrall row. I

The di'liiculty which the present invention is intended to obviate lies in the fact that the central row of holes may not be straight and that the holes perforated near the margins of the tape may not, therefore, be equidistant from those of the central row, thus rendering. the tape defective as a means for message transmission, particularly. when employed with the 'heatstone transmitter. To over? come this ditiiculty, a means has been employed for holding the tape as it passes through the punch head in such lprecise relation to the punches that the central row of holes shall be exactly mit between those lof the marginal rows.

vReferring' to the accompanying drawings,

Figure 1 represents a top view of the feed ,I

wheel, punch head and message fillet. Fig. 2 is a side view showing the illet and one of the two die plates of thev punch head between which the fillet of paper passes While being erforated. Fig. 3 is a perspective view of3 a 'small toothed guide wheel meshing'l with the central apertures of the paper` -wherehy the latter is held in such posit-ion,

as it enters thc punch `h ead, as to bring tlie central perforations nidway between the two rows of punches. lFig. l shows a fillet of paper provided with central holes and such marginal perforations as are employed in telegraphic characters.

Referring to Fig. l, a. is a feed wheel-which vis provided with radial teeth; while c is a i fillet of paper, having central perforations,

which in the operation of the machine first passes over one side of Said wheel, uthence around the punch ,head to an idler or guide roller b, thence over toothed. guide roller c through the punch-head slot between the two housings e, f, over guide roller d, and thence to wheel a., withA whose teeth the central holes, l, ofthe tape again engage..

In the ordinary construction of this machine, the feed wheel rotates upon a vertical axis and the fillet is in a verticalv plane at all positions of its movement from and to the feed wheel, over the Guide rollers, and through the punch head; a though, obviously, the feed wheel might rotate on a horizontal axis, in which case the slot of ythe punch head should be in a horizontal rather than in a vertical plane.

The tape c for use in a VVheatstone transe mitter is ordinarilyT providedwith holes, Z, ten to the inch, along its length, and, obviously, these should be along the longitudinal centervof the paper fillet, and in a straight line. lf the' central holes are in a straight line, and, the tape is supported at the right height at the back or `ingress endof the punch head, the teeth of wheel a, Which rotate ina plane midway between the two sets of punches, must draw the central holes of the fillet throughthe punch head in a line midway between the punches g and h. The punches g are driven inward toward the tape` and through the sameto perforate the lower holes, m, (F ig. 4) While punches h are driven in the opposite direction, or toward the observer looking-at Fig. 1, to punch the holes,

Fig. 2 Shows one of the die plates of the punch headand the relation to the central holes of the apertures therein through which the punches work. As seen, the upper apertures 71, serve as guides for punches h, which,

in the operation of perforating, are thrust through the paper and into corresponding apertures ofthe die plate on the opposite side mesh with the teeth of the feed Wheel a until of the paper; the punches g, however, are guided by apertures in the plate nearest the i observer (Fig. 1), and are driven through the paper into apertures g, F ig; 2.

Owing to the size of the feed Wheel o; and

the necessity for an' adjustable guide roller d,

it is n'ot feasible for the iillet 7c -to come into said fillet is ata considerable distance from the punch head. From this fact, if thev cen-V tral holes were not in a perfectly straight line, or if the tape were held too high or too low as it entered the punch head, the central perforations would not be equidistant vbetween the marginal' holes m and n, Fig. '4.

Byemploying a small guide roller c, as shown in Figsfl and 3, having spur teeth i A rotating in aplane between punches g, h, the

'tape may be heldin such position that even if the central row of holes were not-straight the discrepancy would be only slight. ,'But to this end, the wheel c should be journaled as near the punches as possible.

An adjustable guide roller d is also used i punch head; hat-a sufficient degree of accuracy maybe attained by one such Wheel, as

shown in Figs. 1 and 2.

What we vclaim and Letters Patent is' desire to secure by ll. ,In a perforating machine for preparing telegraphic messages or for lperforating a fillet of paper for other purposes, the eombination of a feed Wheel having periphera teeth, a band of paper provided 'with a ce tral row of apertures, apuneh head, through.

'which said paper passes, provided with punches for perforating apertures in ysare-i fillet on either side at a definite distance from g w.

said cent-ral row of perforations, and a guide z wheel c, having spur teeth, Whichis in close proximity to the punches of the punch head, for holding the central holes of said lille.t in noperfrelation to the punches, as and for the purpose set forth.

2. In a 'perforating machine, the

iillet of paper 7c provided With a central rev:

of perforations, a punch head rovided with 31e a central vertical aperture tirough .which said fillet of'paper passes, two ra ves of punches, 9,7, for perforatingmargina apertures, and a toothed guide wheel c, proximity to the punches of `the .punch head combina tion of a feed wheel a,,hav1ng radialy teeth,`a

1n close whereby the 'central roW of .perforatioi'xs is carried through said .punch head in a line midway between. said ranges and for the purpose set forth.
